Consider a system of two particles having masses m1 and m2. If the particle of mass m1 is pushed towards the mass centre of particles through a distance d, by what distance would the particles of mass m2 move so as to keep the mass centre of the particles at the original position?
d
A wheel of bicycle is rollling without slipping on a level road. The velocity of the centre of mass is vcm, then true statement is
A solid homogenous sphere of mass M and radius R is moving on a rough horizontal surface, partially rolling and partially sliding during this kind of motion of the sphere ?
Total Kinetic energy is conserved
The angular momentum of the sphere about the point of contact with the plane is conserved
Only the rotational kinetic energy about the centre of mass is conserved
Angular momentum about the centre of mass is conserved
O is the centre of an equilateral triangle ABC. F1, F2 and F3 are three forces acting along the side AB, BC and AC as shown in figure. What should be the magnitude of F3. So that the total torque about O is zero ?
